Alpha Trion is one of the oldest living Transformers, and with that age comes a nuanced understanding of his race and their place within the universe. In his youth, he went by the name A3,
and in this time, he helped lead the enslaved Cybertronians in their rebellion against their cruel masters, the Quintessons. As a result, he was instrumental in first establishing Cybertron as an independent planet.
In his older years, he has found a comfortable role in serving as advisor to other Transformers. Though not taking part in the battles of the Great War, he is firmly on the side of the Autobots, serving as a mentor and guide, especially to Optimus Prime and Elita One. He is an enigmatic old robot, though he is known to be the guardian of Vector Sigma and the custodian of its circuit key. His sage-like manner paints him in almost a mystic tone, and possible connections between Alpha Trion, Primus, and the history of Cybertron itself have boosted him into legendary status.
